SPECIFICATION forming`I part of Letters Patent N o. 726,165, dated April 21, 1903. Application filed September 2, 1902. Serial ITo. 121,808. (No model.)

To all whom, it may concern:

Be it known that I, WILBUR'L. HUNT, a citizen of the United States, residing at Audubon, in the county of Becker and State'of Minnesota, have invented certain newfand useful Improvements in Portable Sawmills; vand Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap My invention relates to improvements. in portable sawmills; and its object is to provide a machine of this characterjwhich when not in use may be easily and vquickly-taken apart, folded compactly, and mounted -upon wheels for convenient transportation.

will appear as the nature of the inventionis better understood, the same consists intheconstruction, combination, and arrangement of parts,as will be hereinafter fully described, claimed, and illustrated in the'accompanying drawings, in which- Figure l is a side elevation of my improvedA sawmill as it appears when readyfor transportation. Fig. 2 is an end elevation thereof. Fig. 3 is a top plan view of my machineset up ready for operation, and Fig. 4 is a crosssection on the line 4 4 of Fig. 3.

In the drawings lthe numeral 1 denotes the main frame of my sawmill,upon which the saw' thesaw operator maystand and on which the braces anduninor connecting parts..may be placed when the machine is packed up for transportation. The front axle 8 is pivoted to the front end of the frame bythe king-bolt 9 and carries the supporting-wheels 10 and the draft-pole 11. The rear axle 12 is xed to the rear of the frame and carries the wheels 13.

14 denotes the circular saw, secured to one i tened, connected by the cross-bars 23.

' posite end, to which power may be applied in :any desired manner to drive the saw.

Secured upon the top of the longitudinal sills 5 are two cross-beams 20, which form a log-rollway, as willbe hereinafter described, and between which is located the flooring 2l. pertains to make and use the same.

U.The track-sections 3 and 4, upon which the log-carriage 2 reciprocates, are composed of the longitudinal side bars 22, upon the upper surface of which suitable track-rails are fas- The tw'o sections are fastened together when the device is in operation by the metallic plates or 'cleats 24, boltedto the meeting ends of said sections. The outer end of each tracksection Vis provided with a pulley 25 for the .ffeed rope or cable to run on.

The track-section- 4 is provided near its inner end with a .drum 26 to guide said cable.

The reciprocating carriage2 may be of any desired construction, consisting of a frame- ,Work27, adapted to receive the logs or timber, mounted upon wheels which run on the rails of the track-sections 3 and 4.

' When the machine is set up for operation,

asshown in Fig. 3, the front axle 8 is removed bytaking out the king-bolt 9, the rear `wheels are removed 'from their axle, and the ymain frame l placed in a level position and 'blocked up, if necessary. Itions 3 and 4 are then fastened together by The two track-secmeans of the plates 24 and then secured to the main frame lby the braces or cross-timbers 28, which are bolted to the under side of the longitudinal sills5 and to the under side of the track-sections. An additional diagonal brace 29 may also. be provided to con-- nect the main frame and the tracksection 4. It will thus be noticed that the parts will be securely held together and the tracks will al- 'ways be in line with the mainframe and with each other. The carriage2 `lis thenplaced upon the track and connected up with the feed-cable in any desired manner.

To facilitate the loading of the logs upon the reciprocating carriage 2, I may use the skids or timbers 30 by placing one end upon the sills 5 of the main frame and the other upon the ground. The logs may then be rolled up these skids 30 upon the cross-beams 20 and then down upon the carriage.

When the machine is packed up for transportation, the main frame or truck is adapted to receive all the parts, as shown in Figs. l and 2. The main frame is first properly mounted upon the Wheels 10 and 13. The carriage 2 is then placed upon the top and hold in position by the cross-beams 20, and the two track-sections are then placed upon the top of the carriage. The braces 28 29, the skids 30, and other loose parts are then placed in the truck upon the iioors 7 and 21.

It will be seen that by thus constructing the main frame or truck with a very long body or bed I am able to securely fasten the tracksections thereto to insure their being in line with each other and the saw, and I am allowed to load the track-sections and other parts upon the same for convenient transportation.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood Without requiring an extended eX- planation.

Various changes in the form, proportion, and details of construction may be made Within the scope of the invention without departing from the spirit or sacricing any of the advantages thereof.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

A portable sawmill comprising a main frame detachably mounted upon supportingwheels and having a saw mounted thereon, said frame comprising longitudinal sills connected by a set of cross-bars and platforms upon said frame, one forming in connection with some of said cross-bars a log-runway, and the other serving as a support for the operator, a carriage adapted to rest upon said cross-bars when the mill is not in use, a second set of cross-bars adapted to be secured to the under side of the frame when the wheels are detached and support the frame, and project laterally at one side of said frame, track-sections adapted to be superposed upon the carriage when the mill is not in use and to be supported upon the laterally-projecting portions of said second set of cross-bars wh en the mill is in use, means for fastening the track-sections together, means detachably connecting between the frame and track-sections for bracing and supporting the latter, and detachable inclined skids adapted to be supported by the frame and form tracks up which the logs may be rolled to the runway, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILBUR L. HUNT.
